viewport-lib

viewport-lib is a gpu-accelerated 3D viewport library for rust. The library gives you a renderer, camera, picking-tools, gizmos, overlays, and scene primitives.

Whichever gui library you choose to use (winit, eframe, Iced, Slint, etc.), the integration model stays the same in each case:

• your application owns the window, event loop, and tool state;
• viewport-lib owns rendering and viewport-side maths.

WARNING: viewport-lib has only recently been extracted as a stand-alone library from a separate project and the API is still somewhat unstable.
